Electric high-temperature steam regulating valve
Electric high-temperature steam regulating valve
Product details
ZDLPGElectric high-temperature steam regulating valveIt is composed of a 3810 series electronic electric actuator and a high-temperature regulating valve body, which includes feeding and clothing functions and accepts unified 4-20mA or 1-5V? The standard signal of DC converts the current signal into a corresponding linear displacement, automatically controls the opening of the regulating valve, and achieves continuous adjustment of process parameters such as pressure, flow rate, temperature, and liquid level of the fluid in the pipeline. The regulating mechanism of the electronic electric high-temperature regulating valve adopts a balanced valve plug structure. The electronic electric high-temperature regulating valve has the characteristics of good valve stability, low vibration, low noise, low sensitivity to temperature, small allowable pressure difference, and high temperature and pressure. Electronic electric high-temperature regulating valves are widely used in situations with high flow rates, high temperatures, and less stringent leakage requirements.
The 3410 series switch type electric actuator can be configured to only control the on/off of high-temperature and high-pressure media.
Explosion proof electric actuators can be configured to meet harsh working conditions and hazardous, flammable, and explosive environments. (For detailed information on electric actuators, please refer to the electric actuator section of our company's website or inquire with our company)
